Charmonium production in heavy-ion collisions

Xingbo ZhaoTexas AM

We investigate charmonium production in relativistic heavy-ion
collisions via a rate equation which comprehensively describes
dissociation and regeneration (via $c$ and $\bar c$ quarks)
through QGP anined from primordial production including pre-equinsport equation (for
primordial production) and a blast-wave approach (for
regeneration) are employed to study the transverse momentum
distribution of charmonia. The influence of various mechanisms on spectra and
rapidity distribution at different collision energies are
investigated, and tested with applications to experimental data.
